Step 1: Prepare The Crust

Take two slices of soft white bread and arrange them to line a four inch ovenproof dish, cutting the bread in whatever way makes it more or less fit.

Brush the bread with vegetable oil (or rendered bacon fat if you have it), press another identical dish on top, then place it on a metal tray in the oven (180C) for 20 minutes, or until the bread is pale golden and crispy.
